Abstract Engineering company operates a wastewater collection and treatment facility for their clients in Myton, Utah. The facility receives fracking and produced wastewater from various pumping stations, and then treats the water for disposal at the injection well located on site. Electrocoagulation followed by two clarifiers and 5 micron filter was used. Since many particles float or just ...

Winery wastewater treatment at Hess Collection Winery (Napa, CA) features floating horizontal brush aerators, data logging, and computer monitoring and control to simplify required water quality reporting. Since installation in 2001, Hess Collection Winery has never been out of compliance with state discharge limits. Wineries generate a strong organic wastewater that is highly depending on ...

Three models were compared to determine their ability to accurately predict emissions from two wastewater collection system components; gravity flow reaches and drop structures. Models investigated included the INTERCEPTOR Model, TOXCHEM+ and WATER9.Data used to perform the analysis were obtained from published literature. A total of 128 individual runs per model were completed in performing the ...

Management of Corpus Christi’s Wastewater Collection system is improving customer service and the underlying collection system infrastructure by using a computerized work and asset management system (WAMS) linked to the City’s Geographical Information System. The system provides a computerized record of all customer calls for service and a history of all collection system work performed ...

This paper provides a comprehensive summary on modelling of micro-pollutants' (MPs) fate and transport in wastewater. It indicates the motivations of MP modelling and summarises and illustrates the current status. Finally, some recommendations are provided to improve and diffuse the use of such models. In brief, we conclude that, in order to predict the contaminant removal in centralised ...

The assessment of nuisance odour problems and the application of an effective odour management programme for the associated industrial activity may be achieved using a representative odour wheel and Odour Profile Analysis methodology. The odour wheel is a very useful tool for conducting odour quality control monitoring and developing a constructive dialogue regarding nuisance odours with the ...

In small and rural communities, the installation cost of conventional gravity-flow collection systems is often very expensive due to the presence of rocky terrain, high water table, unstable soils, extremely flat terrain, which may impose substantial difficulties in construction. Pressure, vacuum and septic tank effluent gravity collection systems are among the alternatives sewers used most ...

This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

Short Abstract (less than 100 words) In-Pipe Technology (IPT) employs sewer collection system bioaugmentation treatment to enhance the sewer biochemical processes by improving the microbiology in the collection system, and provides improved microbiology to the wastewater treatment plant (WWTP). In this presentation, the effect of IPT sewer collection system bioaugmentation on sewer ...

In late 2015 Reliant Water Technologies introduced the Wet Well Wizard, an aeration tool for the wet wells in collection systems. During 14 months of field testing the patent pending Wizard System, the primary objectives were to eliminate FOG (fat, oil and grease) caps and to reduce H2S, eliminating it if possible. All trials were proven excellent with very few changes to the product that ...

In this study, three good biofilm-forming yeast strains, including Candida viswanathii TH1, Candida tropicalis TH4 and Trichosporon asahii B1, were isolated from oil-contaminated water and sediment samples collected in coastal zones of Vietnam. These strains were registered in the GenBank database with the accession numbers JX129175, JX129176 and KC139404 ...

Summary A mid-western township is responsible for operating and maintaining a combined sewer collection system consisting of 150 miles of pipeline and 28 pumping stations. The township does not treat the wastewater, instead contracting with a neighboring city for this service. The township has two final lift stations that transfer the collected wastewater to the neighboring system ...

To investigate the occurrence and bioaccumulation of organic contaminants of emerging concern (CECs) near four major wastewater ocean outfalls in the southern California Bight, more than 75 pharmaceutical and personal care products, current‐use pesticides, and industrial/commercial chemicals were analyzed in sediment and liver tissues of hornyhead turbot (Pleuronichthys verticalis) using gas ...

ABSTRACTIncreased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower duringbioaugmentation. RBCOD increases could potentially improve biological phosphorus or nitrogen removal. Lowered sulfides in the influent could lower corrosion and odors in the collection system ...

This study evaluates the removal of nitrogen compounds from wastewater in modified, small diameter gravity slope (SDGS) pipes during its conveyance. A 13-meter long, closed loop, wastewater collection network was designed and built at laboratory scale. The modified SDGS consists of Polyvinyl Chloride (PVC) tubes with perforated plastic netting fixed to the inner surfaces, to enhance biofilm ...

In 2004 the wastewater treatment plant in the Town of Orange Park had a very unique problem. The Town was in violation of the current Water Quality Based Effluent Limits (WQBEL) permit while they were simultaneously planning for the even more stringent, Basin Management Action Plan (BMAP) permit to take effect in 2008. The Town needed to address both long and short term wastewater treatment ...

ABSTRACT The collection and conveyance of sanitary wastewater is a principal tenet of sanitary engineering that has helped move developed countries into the modern urban age. The focus of collection system agencies has historically been to convey wastewater to treatment facilities. The operational practices of these agencies have generally been geared toward infrastructure maintenance and ...

Abstract Dry-scrubbing systems have been used for many years to control odors in wastewater applications. The systems have ranged in size from larger multiple bed scrubbers for force mains and large pump station applications to smaller single bed systems and modular systems in small wet wells, motor control centers, and other areas. Two reasons for their continued use are simplicity of ...

On October 1, the Commonwealth of Massachusetts’ ban on landfill disposal of commercial organics from establishments generating one ton or more of food waste per week goes into effect. On the front lines of helping these businesses and institutions comply are organics haulers, many of whom have been offering their services for years. “Seven years ago, we were servicing about two dozen ...

Romtec Utilities designs and supplies pump stations for many different types of applications, including leachate collection and removal systems. Leachate pump stations are required whenever water passes through a bed of solids and extracts contaminating elements. The most common scenario for collecting and pumping leachate is for landfills, but there are industrial ...
